CONNECTION FOR PIPES.

Specification of Letters Patent.

Patented Oct. 19, 1909.

Application filed .Tune 12, 1908. Serial No. 438,141.

To all whom it may concern:

Be it known that I, TIMOTHY D. GLnnsoN, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented new and useful Improvements in Connections forPipes, of which the following is a specification.

This invention relates to a flexible joint or connection for pipes whichconnection allows of lateral movement of the pipes but will preventtheir being pulled apart or separated.

This invention is to be applied chiefly to pipes or conduits which aresunk in a river but it can also be applied to conduits not in water.

With conduits or pipes simply connected by lead or the like and laid orsunk in a river it frequently occurs that the tide of the river willcause the pipes to be moved, which movement will loosen the lead andcause the pipes to be separated or are forced apart causing them toleak.

This invention is designed to overcome such defect. According to thisinvention the pipes are connected in the usual way and have lugs aroundwhich lugs are passed an endless chain or flexible connection. Thus thepipes can move laterally but the chain prevents the pipes fromseparating or being forced apart.

This invention is set forth in the following specification and claimsand illustrated in the annexed drawing, in which:

Figure 1 is a face view of a pipe connection embodying this inventionand Fig. 2 is a section along line 00 m Fig. 1.

In the above drawing the letter a shows a pipe on which is secured aniron band I) which however is no part of this invention. At 0 are shownlugs adjacent to each other on the pipes a and 0?. These lugs c areintegral with the respective pipes and are formed with the latter whencast or molded. These lugs c are hook shaped as shown at c (Fig. 2). Anendless chain is shown at 7 which engages the hook shaped lugs c.Instead of a chain I could also use a cable or wire rope or iron band.This chain or connecting means will prevent the pipes at and d frombecoming separated while at the same time it will allow lateral movementof the pipes.

As shown in Fig. 1 when the pipe d is moved either to right or left thechain 7 slips or moves over the lugs 0 in the pipe a. When the pipe at(Fig. 2) is moved to right or left the chain moves over the lugs on thepipe d. Thus it is readily understood that the pipes can move laterally.

I-Ieretofore when the pipes were moved .laterally a few times theybecame separated.

This cannot happen with a connection of this invention inasmuch as chain7 being wound or placed around the lugs 0 will prevent the pipesbecoming separated.

The lugs c are adjacent to each other and when the pipes are securedtogether they should set so that the lugs on pipe a face in the oppositedirection to the lugs on pipe cl.

Instead of chain f an iron band made in four pieces so shaped as to fitthe curves of the pipe sections and connected by means of bolts can beused to hold the pipe sections together.

Now what I claim is:

1. In a connection, two pipes, adjacent lugs on each pipe and a flexibleconnection adapted to engage the lugs on each pipe to prevent separationof the pipes said lugs being arranged out of line and alternating witheach other on the respective pipes so as to cause the flexibleconnection to assume serpentine form and allow lateral movement of thesame said lugs being rounded to allow slipping of the connection.

2. In a connection, two pipes, adjacent hook shaped lugs on each pipeand an endless chain engaging the hook shaped lugs on each pipe saidlugs being rounded and corn vexed to allow slipping of the chain.

3. In a connection, two pipes, adjacent hook shaped lugs on each pipe,and endless connecting means engaging the hook shaped lugs to hold thepipes together and prevent separation of the same, the said lugs beingintegral with the respective pipes said lugs being smooth and rounded toallow slipping of the chain.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
